Description of LABS
Taiwan is located downwind of East Asia and Southeast Asia, which are major air pollutant source regions. As result, Lulin Atmospheric Background Station (LABS), was constructed to study the trans boundary transport of these air pollutants and their impact on Taiwan.
LABS is located at 2,862 meters above sea level on top of Mt. Lulin in central Taiwan. Mt. Lulin is part of the Central Mountain Range and overlooks beautiful and warm grassy fields inside Yushan National Park. Because of the high altitude of LABS, measurements there are not affected by local pollution from factories, traffic and other domestic sources; rather, it is strategically located to monitor long-range transported air pollutants from the Asian continent.
The main objective of LABS is to investigate the long-term trends and variations of regional air pollutants entering the western North Pacific and to study the local impacts on Taiwan and regional impacts on air quality, atmospheric chemistry, radiation, and climate. This objective is achieved by a suite of continuous measurements at LABS, including precipitation, solar radiation, aerosol concentrations and optical properties, and trace gas and atmospheric mercury concentrations.
Scientific work at LABS encourages interdisciplinary collaborations among atmospheric scientists, chemists, and environmental scientists to perform important measurements, apply novel data analysis techniques, and construct long-term databases. Thus far, while hosting several international experiments (e.g. Seven-South East Asian Studies, 7-SEAS), collaborators at LABS have included the US Environmental Protection Agency (EPA), National Aeronautics and Space Administration (NASA), National Oceanic and Atmospheric Administration (NOAA), and Japan Mt. Fuji research group.
